Mixed material layer, method for production of the mixed material layer, solid battery, and method for production of the solid battery

摘要

A solid state battery excellent in pressure formability is provided. A positive electrode composite material layer (100) includes sulfide glass (31) unheated and a positive electrode active material (110). The sulfide glass (31) and the positive electrode active material (110) are pressure-formed and in contact with each other. A negative electrode composite material layer (200) includes sulfide glass (31) unheated and a negative electrode active material (210). The sulfide glass (31) and the negative electrode active material (210) are pressure-formed and in contact with each other.
